Silica is regarded as a jack of all trades when it comes to plants, and some even refer to this nutrient as a “Supervitamin” for plants. Silica is crucial to any grow room, but especially a soilless or hydroponic operation.
So what exactly can silica do for your plants?
- Stronger Cell Walls
- Bigger and Stronger Stems
- Increased Resistance to Environmental Stress
- Increased Resistance to Pathogens and Pests
- Improved Metabolic Functions
Experts suggest that silica be utilized in a hydroponic system throughout the entire life of the plants, from seedling to harvest. While hydroponic systems will rely more heavily upon silica supplementation, it is also useful to supplement plants grown in soil.
Silica can be applied either as a root feed or as a foliar spray, but studies show that plants can absorb more through foliar feeding than through the root zone. Regardless of how you apply the silica, it is important to note that silica can raise the pH of your plant, so it is best to add it as the last nutrient when feeding.
